ELECTRIC JACQUARD-MACHINE.

To all whom it may concern.

Be it known that we, KARL FANTA, AU- GUST REGAL, HANS Vnrrzn, andNORBERT \Vnssnnr, citizens of the. Austro Hungarian Empire, and residingat Vienna, Austria-Hungary, have invented certain new and usefulImprovements in Electric J acquard-Machines, of which the following is aspecification.

Our invention relates to improvements in machines for reproducingpatterns, figures, pictures and photographs, electric currents beingemployed.

The invention will be described with reference to machines for textilepurposes, and particularly to an electric jacquard machine for makingfigured fabrics of all kinds without using cards, such as are describedin the United States Patents Nos. 983,862 and 1,017 ,068.

Fig. 7, and Fig. 10 is a rear half-elevation of the mechanism fordriving said controlling switch; Figs. 11 and 12 are elevations showingour improved needle and knife frames, and Fig. 13 is a diagrammatic viewof our improved means for varying the size of the shed.

Referring to Fig. 1, a designates an example of a pattern cylinder whichis mounted on a rotatable roller and comprises the electro-conductivefigure port-ion Z) and the electro-non-conductive ground portion 0. clare the contact-pieces or feelers which receive the current and areconnected with electro-conductive bars 6. Each of these bars 6 receivescurrent from a battery B over the brush f on the pattern cylinder whenthe feeler d associated therewith is on a conductive portion of thecylinder, and is currentless when its feeler is on a nonconductiveportion. In order, however, to obtain a weave for the ground of the webwhen a bar 6 is currentless, additional bars 9 are arranged parallel tothese bars and are electrically connected directly with the battery 13,.From the bars 6 the current is supplied to the various solenoids h bymeans of double brushes 2' which slide on the one hand on these bars,and on the other hand on the various contact-blocks k and are movedsynchronously with the feelers d. The solenoids h are employed forexample to control the needles which effect a lifting or a leaving innormal position of the heddles, and thus of the warp threads, and asshown for example in U. S. patent to Regal No. 1,017,063. When the bars0 are currentless, current can be supplied by the second battery B tothe solenoids it over the bars 9 by means of the double brushes 1 whichare coupled to, but insulated from the double brushes 2'. From thesesolenoids the current flows over the transverse bars. m and longitudinalbars a of the line-selector, which must be connected according to thedesired weave, and from here it returns in the one case over thefigure-weave switches 0 to the battery B and in the other case over theground weave switches p to the battery 13,. These weave controllingswitches 0 and p are opened and closed in known manner by means oflifting cams or the like which are arranged successively in chain formand give combinations suited to the kind of weave desired.

Fig. 2 shows an example of a device for machines of the characterdescribed in which, in accordance with our invention, the solenoids h,the line-selector M comprising the bars m and n, and the row ofcontact-blocks is are united as one unit in a single frame. As clearlyshown in this figure, the various parts are held together by suitablyformed iron bars g, and the line-selector itself can be readilyexchanged because it is held in resilient contact-clamps r only by meansof projections of the transverse bars m, which are slid into the clamps,and can be removed by being withdrawn from these clamps. The solenoidsare arranged in a series at one side of the frame and opposite to themat the other side of the frame the contacts is are arranged, one foreach solenoid. The line selector comprising trans verse and longitudinalbars m and n is disposed between the solenoids and the contacts. Thesolenoids may be connected in groups as desired, and the longitudinalbars 40. carry at one end thereof bored contact-blocks 5 for connectingtogether those lineselectors arranged one above another which belong tothe various groups of solenoids. The electrical connections between thevarious parts are partly shown in Fig. 2 and will be clearly understoodby reference to the diagram Fig. 1. The conductors leading from theseveral contacts of the step switch which they constitute, to therespective solenoids h are suitably housed together on each side of theframe. Each solenoid his connected to the binding post or connection 7of its corresponding transverse rail m of the line selector. By means ofthe bored contacts 5, above referred to, disposed at one end of thelongitudinal rails n, the line selectors of the several groups ofsolenoids are connected together, and the first or the last selector,for example, is connected with the switches 0 and 79. Our invention isnot limited to the specific arrangement shown in Fig. 2, but this figureis intended only as an example of a principle of construction, which maybe followed out and enlarged upon in numerous different ways, withoutdeparting from the spirit of the invention. Owing to the whole of thecooperating elements being compactly arranged in this manner in a numberof groups which are incorporated in a frame, it is possible toreadily'exchange damaged parts because the various groups containingdefective elements can be simply replaced by spare groups, 11. a. spareunits, kept in stock; the frequently tedious search for, and replacementof, a damaged element can thus be carried out elsewhere withoutdisturbing the operation of the apparatus.

In another embodiment of our invention we unite in a single unit, asshown in Figs. 2 and 2 all those solenoids, which are each associatedwith one of the feelers at the pattern cylinder, with the appertainingmultiple switch and, if need be, with other elements. Since when a faultappears in the web, the feeler which is touching the correspondingpartof the pattern cylinder must be immediately discovered, the saidarrangement has the special advantage that the faulty unit is in thismanner immediately determinable and can be exchanged in a very shortspace of time.

In a further embodiment of our invention, as shown in Figs. 2 and 2, weunite in one single unit as many solenoids or magnets with theircontact-blocks as mechanical elements make up one group in the usualgrouping at the textile machine in question. For example, it iscustomary in jacquard apparatus to assemble the whole of the needles ingroups in such a way that each standard size of the machine is builtwith a corresponding number of such groups, for example, an SOD-machinewith 2 groups (socalled EO-machines), a 2000machine with 5 groups, andso on. Owing to this arrangement the incorporation of our new appara tusin existing types of textile machines is very simply carried out withoutsuch machines needing to be remodeled. In the unit shown by way ofexample in Fig. 2 the solenoids h and the contact-blocks 7c of themultiple switch are connected in series. This arrangement isdisadvantageous in that it is not possible to checkor exchangeindividual solenoids without taking the unit from the framework of themachine. This difliculty is obviated by arranging that thecontact-blocks of the multiple switch and the solenoids on the same sideof the unit are so superposed or juxtaposed that each of these elementsis freely accessible.

Since the individual solenoids have in every case a comparatively largeamount of self-induction provision must be made for counteracting itseffects by suppressing or obviating sparking at those places at whichthe circuit is broken, in the present case at the multiple switch and atthe pattern cylinder. To this end, as shown in Fig. 4, we connect inparallel with the winding of each solenoid a bifilar winding a in whichthe current can flow and destroy its own field. A further improvement wemake in the con struction of the solenoids or electromagnets consists inproviding on the solenoid or out side the same, 0. g. at the mouththereof, a suitably formed clamping spring o whose function is toreceive and damp the shock and recoil of the solenoid-core 1w (Fig. 3),for the purpose of securely holding the core w in its attracted positionand preventing it from becoming accidentally loosened, an effect whichmight result in faulty operation of the machine or in faulty work beingproduced thereby. The means for returning the cores to normal positionforms no part of my present invention and hence the same is notillustrated herein, but those skilled in this art are familiar withdevices suitable for this purpose, as for example that shown in U. S.patent to Regal, No. 1,017 ,063. As will be understood from Figs. 3 and4, when the core to is drawn into the solenoid, the spring a; will slideon the conical portion and rub against the larger portion of the core10, will check the motion thereof, and will receive the shock of andfinally securely hold the core. Consequently, the solenoid-core isprevented from subsequently becoming loose owing to the vibration of themachine.

As already stated the unit-frames, one of which is illustrated by way ofexample in Fig. 2, and which comprise groups of solenoids, lineselector, and the appertaining contact-blocks, are arranged one aboveanother and, when the number is large, side by side. We accordinglyprovide the com mon contact-apparatus illustrated in Figs. 5, 5 and 5for the various rows of contactblocks in order to transmit the currentbetween these contact-blocks and the bars 6 or the source of current Band between these contact-blocks and the source of current 13,. The rowsof contact-blocks or the appertaining unit frames are in this casearranged one above another and in two piles side by side. Thecontact-apparatus (Fig. 5) comprises two systems of brushes, one ofwhich systems consists of double brushes '5 insulated from one anotherand from the frame of the machine; one brush of each of these doublebrushes slides on the multiple switch blocks and the other on thecontactbar 0 parallel and opposite to the various multiple switchblocks, as may be seen from the diagram Fig. 1, and serve to supply thecurrent from the battery B to the solenoids when the feeler (Z is on aconductive portion of the pattern cylinder. The other system consists ofthe brushes Z which are uninsulated, 2'. c. are conductively connectedtogether and with the framework or the frame 1 of the contact-apparatus,and as mentioned above, move synchronously with the brushes 5 over therows of contact-blocks. The current flows from the battery B, to thebrushes Z owing to one pole of the battery B being connected with theframework of the machine. By means of such an arrangement current can besupplied to each solenoid from the source of current B or B assumingthat the appertaining weave forming switch 0 or p is, at the moment theappertaining contact-piece 7c is being contacted, connected through atthe multiple switch block by means of a brush of the one or the othersystem, and the path of the current on the pattern cylinder a is notinterrupted. In order that the machine may be operated correctly thiscontact-apparatus must move synchronously with the pattern cylinderfeelers (Z, except that the path traversed by the brushes is a largemultiple of the path along which the feelers at the pattern-cylinderhave to move. Now in order to obtain the necessary gear-ratio betweenthe two motions several toothed wheels have heretofore been employedwhich, however, owing to the unavoidable back-lash between the teeth,cause in practice undue inaccuracy. It is obvious that owing to thecomparatively very short path of the feeler (Z very accurate adjustmentmust be able to be made. According to our invention we obtain thenecessary gear-ratio and the required precision by means of a pluralityof preferably adjustable levers, as shown by way of example in Fig. 6.Here 4 designates the contact-apparatus shown in Fig. 5, and 2 theguide-rods for the same. This contact-apparatus is engaged by aforked-lever 5, which is fulcrumed at the point 6 and is rocked by acam-disk 7 having a groove 8 and block 9. To the point 10 of the lever 5is slidably and rotatably fastened the lever 12 which can rock about theaxle 11 and moves the pattern-cylinder feelers d which are carried bymeans of suitable devices in the slot 13 and are adjustable in variousdirections. In order to obtain practically exact synchronism between thepattern-cylinder feelers and the contact-apparatus, it is obviouslynecessary that the center of oscillation 11 of the lever 12 be locatedexactly vertically above that of the lever 5, and it is only with a viewto clearness and simplicity that the figure illustrates an arrangementwherein this condition is not fulfilled. When this device is operated,the contactapparatus will move a distance equal to the length of oneblock of the multiple switch, while the point 10 moves a very muchshorter distance. The motion of the point 10 is again reduced to asmaller motion by the point of application of the common carrying deviceof the various pattern-cylinder feelers (Z being arranged near thefulcrum 11. Since the gear-ratio can be readily chosen as desired inthis manner and as disturbing play in the mechanism can be avoided, therequired precision is therefore obtained and the desired conditions arefulfilled.

In the positive transmission of motion between the weave switches andthe pattern cylinder there must be great accuracy and any sliding orslipping must be avoided For this purpose we have constructed a new formof rubbing drive for adjustable ratio of transmission, the rubbing partsor surfaces of which are provided with corresponding wart-likeprojections and depressions, which engage with each other in opcr ationand prevent absolutely any lagging of one part'behind the other. In theexample illustrated in F 7 and 8, the rubbing wheel 14L of the drive hasdepressions 15, while the other rubbing wheel 16, adjustable on itsaxis, has inserted fingers 17, which engage with the correspondingdepressions during the operation of the wheels or disks against eachother.

In order to provide the fabric manufactured on the machine with therequired pat tern and ground, as mentioned above with reference to Fig.1, the so-called weave switches are required which openand close thevarious circuits to the solenoids without regard to the pattern to bewoven but only with regard to the required weave for the fabric (Figs.1, 7 and 9). These switches are opened and closed, as is well known, bymeans of lifting members arranged in a row like a chain, 2'. e.so-called lifting rollers. According to our invention the weave switchcomprising the preferably readily exchangeable lifting members 18 (Figs.7 and 9) arranged in the form of a chain is constructed in such a mannerthat, in respect to the sequence, all even-numbered chain-pins, thus the2nd, 4th, 6th, 8th, carry the lifting members for the ground switches 79and all oddnumbered chain-pins, thus the 1st, 3rd, 5th, 7th, carry thosefor the pattern switches 0, or vice versa, and the feed mechanism 19always advances two of such members or links simultaneously, for thepurpose, firstly, of accommodating both the movable c011- tact-piece ofthe weave switch o for the figures and those of the switch 7) for thegroundwork in a single casing, or as it were in a common switch, eachtwo of such contactpieces being arranged opposite to one another ifdesired at the same level, and, secondly, of being able to actuate themby means of a single chain. According to our invention, contact is madeat the weave switch itself by the contact-pieces 0, p of the switch,which are preferably made in the form of plates, being pressed by thelifting members 18 of the chain against resilient contact springs 20. Assoon therefore as a roller 18 comes below one of the contactpieces 0 or79, the latter is pressed against the contact spring 20 and the circuitis closed, whereas when there is no roller on the chainp-in, the movablecontact-piece remains at rest and the circuit therefore is not closed.The electrical connections of the weave switch will be readilyunderstood from Fig. 1. The weave switch is driven by the same shaft asdrives the cam disk 7 (Fig. (3) by means of a chain and sprocketavheels21 (Fig. 7), the gear-ratio being 1:1. On the axle 2 of thesprocket-wheel 21 (Fig. 7) is mounted the driving disk 23 having twodriving pins 24:, which drive the wheel 25 and, consequently, thefriction-wheel 14 and the feed mechanism 19 of the weave switch, thegearratio being 1:2. 7

I t is necessary that the weave switch and the pattern-cylinder berotated twice while the eccentric 7 makes one revolution, because thenthe contact-apparatus has moved to-and-fro over the multiple switchesand because this operates during both its outward and its returnmovement and therefore two weft threads are inserted during this time,so that two cross-weaves must result. After the feed motion has takenplace it is absolutely necessary that both the driving mechanism of theweave switch and the pattern-cylinder be immovably held in posi-- tion.Heretofore their drive and retention have been effected by means oftoothed wheels, levers, ratchet-wheels and detents, an arrangement whichowing to the amount of play arising must be unsatisfactory. Our improveddriving and retaining mechanism preferably comprises a star-wheel 25, asocalled Maltese cross, mounted on the axle 26, by means of which boththe gear ratio and the desired locking are obtained (Fig. 10). TheMaltese cross 25 is driven by means of the two driving pins 24: of thedisk 23, one of which engages in the notches 27 and rotates theMaltesecross one tooth, provision being made for this by suitably forming orrecessing the disk 23. After this rotation of the Maltese cross, theconcave outer face 28 of one arm of the cross abuts against the circularperiphery 29 of the disk 33, whereby the said cross is prevented fromrotating further, and cannot indeed rotate in either the one directionor the other. Hence during each half revolution of the disk 23 theMaltese cross is fed one tooth by means of the pins 24 and after eachperiodic sudden advance is held locked. The desired object, to suitablyadvance the weave stitch and the pattern-cylinders in steps and to lockthem after each movement, is thus attained in a very simple manner.

Figs. 11 and 12 illustrate the arrangement of lifting-hooks 30, theneedles 31 and the separators 32, and guides appertaining thereto, aswell as the lifting frame 33 and lifting-hook support 34. In order toprevent the needles 31 in one horizontal row from getting out of place,so-called separa-' tors have been arranged between the needles.Heretofore, between each pair of adjacent needles a pin having a widthcorresponding to the distance between the needles was inserted betweenthem. This construction is however disadvantageous in that, when such apin is removed, the needles directly adjacent to one another are nolonger kept apart but can come together, which would cause considerabletrouble on the exchange of such needles becoming necessary. According toour invention, for keeping the needles at a correct distance apart 'weprovide a guidepin of special form for each of the vertical rows ofneedles in such manner that each needle is as it were embraced as by afork by these guide-pins. When therefore a guide-pin is removed, theneedles previously embraced thereby cannot have mixed with those in thesame horizontal rows.

A further feature of our invention is embodied in the specialarrangement of the knives 85 in the lifting frame 33. Heretofore thesehave always been fast in their frame, an arrangement which is founddisadvantageous when it becomes necessary to exchange the hooks 30. Wetherefore provide knives which are movable and are preferably connectedwith rods 37 by means of suitable joints 86, so that when these rods arepulled, the knives can be readily moved from the working position 38indicated by dotted lines into that indicated by full lines, and whenrequired can be entirely removed from the lifting frame. Exchange of thehooks 30 is thereby considerably simplified and facilitated.

In order to vary the size of the shed in looms, 2'. e. to varythe heightof the upper shed and depth of the lower, the one arm of the two-armedlever employed for the shed has heretofore been shortened or lengthened,or the driving eccentric has been exchanged, in which case a suitableintermediate lever had to be employed. According to our invention, wevary the size of the shed by shifting the fulcrum of the two-armed leverfor forming the shed. One embodiment of this feature of our invention isillustrated in Fig. 13. The two-armed slotted levers 41, 42 which drivethe lifting frame 33 and hook-support 34 respectively by means of theguide rods 89, 40, permit an adjustment of their fulcrum 43, 44, wherebythe gearratio of the rocking motion produced by the eccentrics 45, 46,and the antifriction rollers 47, 48 of the levers 41, 42 hearing thereoncan be varied. It is evident that no intermediate levers are required,and that by a small adjustment of the fulcrums 43, 44, a considerablechange can be made in the size of the shed which is formed.

The herein described devices are not limited in employment, as alreadymentioned, to electric jacquard machines producing figured webs, but canobviously be correspondingly applied to and employed in all machines forreproducing figures, patterns, designs and the like by means of theelectric current.
